CAR-WHEEL.

SPECFICATION forming part of Letters Patent No. 340,845, dated April 27l1886.

Appliration filed February 3. 1856. Serial No. 190,706. (No model.)

To @ZZ whom, it may concern.-

Be it known that we, WARREN J. WILLITs and EDWARD B. LiNsLEY, both ofrlhree Rivers, in the county of St. Joseph and State of Michigan, havein-vented a certain Improved Car-Wheeh of which the following is aspecification, reference being had to the accompanying drawings, inwhich- Figure l is a side view; Fig. 2, an opposite 1o side view, andFig. 31's a diametrical section. Fig. 4 is a view ot' a canwheel bodysuch as shown in United States Patent No. 263,732; and Fig. 5 isadiametrical section of the same, showing the metal hub e and ourimproved tire.

I 5 Our object is to produce an improved carwheel of the kind in whichthe tires are provided with the ordinary rail-flanges of railwaycarwheels projecting outwardly, and another flange on the opposite side ofthe tire projectzQ ing inwardly, the latter serving in part at least tobolt the tire to the body-of the wheel; but in making our tire weprovide an inwardly-projecting flange not only upon the inside of thetire, as has been heretofore done, but

upon the opposite edge of the tire from the outwardly-proj ectingrail-flange, and to serve as the exclusive means lor boltiug the tire tothe wheel-body.

Our design is to produce a light wheel of 3o the generalcharacterindicated for use chiefly in hand-cars or velocipcde hand-cars,the body of which may be of wood, paper, or other light substance, withor without a metal hub. Our tire might of course be used with a metalbody; but for lightness and chcapness we prefer other material.

"We make our tire from the ordinary plate iron or steel, and either frombars rolled to desired width and thickness, and after being 4o cut toproper length welded into a plain ring, or from a plate out of which maybe out a flat ring, either of which can be pressed and bent to shape atits opposite edges to form the flanges.

It will be observed that the inwardly-projeeting flange ofthe tire isbolted only to the outer edge of the body of the wheel. This is becauseof the fact that we make only a light wheel, not required to sustainenormous 5o weights, and hence do not require any separate metalring onthe side of wheel-body 0pposite the flange for the bolts to passthrough, and do not require any shoulder to accommodate such a ring orplate upon the tire. Our tire is a mere shell into which the wheel-bodyis placed, and bolted only to the inwardlyprojecting flange. By thismeans we reduce the metal necessary to constitute the tire4 to. theminimum, whereby both economy of inaterlal and the least weight possibleare se- 6o cured, and at the same time we have suiiieient strength f orthe pu rp oses of the wheel we make. Heretofore, so far as we are aware,the bolts have passed through the body of the tire, or else a ring` orplate shouldered onto the tire 6 5 Vopposite to the inwardly-projectingflange E,

has been provided, and has been necessary. By the use of our tire, madein the manner described, the expense and other disadvantages of suchconstructions are avoided. 7o

Heretofore tires having flanges of the charactor specified have beenmade either as shown in Patents Nos. 104,053 and 322,276 by casting orelse rolling them from ingots or billets, the flanges being rolled fromsolid blocks. Our plan is much cheaper and better, and, in fact, is theonly one practicable for thin light tires, such as we desire to make.

XVe forni the body of the wheel preferably of wood, either using spokesdriven into a 8o wooden hub, as shown in Fig. l, or triangular piecesplaced upon an iron hub and forming a web, as shown in Fig. 4, and thensecure to this central portion the tire by bolts passing through theouter edge of the wheel-body, and only through the inwardly-projectingrlange of the tire.

Referring to the letters upon the drawings, A indicates the hub, ofmetal or wood; B, the spokes, or it may be a web, and C the felly or grim of the body of the wheel.

D indicates bolts passing through the rim of the wheel-body and theinwardly-projecting flange E of the tire F, which is also provided withthe usual rail-1lange, G. These flanges 95 are formed by pressing andbending the opposite edges of a plain band of wrought metal or steelinto shape, or from a disk of plate metal, as above indicated.

XVe thus obtain a tire of substantially nniroo form thickness of metalin its tread portion and in its anges that has the advantages of wroughtmetal, and the thinness and lightness adapting it to such minimum costand minimum fastening means for securing it to the wheel-body as arevery desirable in light wheels designed for use in hand-cars, Sie.

XVe are aware of the United States Patents of Stiinpson, granted August23, 1831, and of Hoover, granted July 15, 1884, No. 302,203, forcar-wheels, and we do not claim the form of tire or the parts combinedwith the form of tire therein shown; but our invention is limited to thepeculiar improvements above described and succinctly deiincd in theVappended claims.

That we claim to be new, and desire to secure by Letters Patent of theUnited States, is*q 1. lVrought plate metal tire having out- WARREN J.WILLITs. EDWARD n. LiNsLEY.
